HILMEBA N. ENHOLM, OF BUSHN'ELL, ILLINOIS.

WATEB-ELEVATOB.

To all 'whom it may concern.'

Be it known that I, HILMEir N. EirHoLM, a citizen of the United Statesresiding at Bushnell, in the county of Mc enough and State of Illinois,have invented certain new and useful Improvements in Water-Elevators, ofwhich the following is a specifica tion.

This invention seeks to provide a simple and easily operated mechanismwhereby water may be raised from a well.

The invention is illustrated in the accompanying drawings, in whichfFigure 1 is a view partly 1n section and partly in side elevation of myimproved mechanism in position in a well;

Fig. 2 is an enlarged sectional view of the cylinder through which thelifting buckets or floats pass to enter the water.

The well 1 may be built in any wellknown manner and is provided with acurb Yor hood 2 in the sides of which is mounted a shaft 3 carrying asprocket wheel or pulley 4 around which is trained an endless chain offloats or buckets 5. The curb 2 is equipped with a delivery spout 6extending laterally from one side and a gate 7 may be provided toprevent the access of dust or other matter to the well when the elevatoris not in operation.

' Within the well, I provide a plurality of brackets 8 to which I securea pipe 9 which provides a vertical member 10 having an open upper endlocated above the normal level of the water, indicated at 11.

At the lower end of the said inlet member 10 lis a return bend 12 whichconnects the pipe with a vertical cylinder 13, said c linder beingprovided with an outer wal 14 and an inner wall 15 consistin ofsuperposed axially alined sections. getween the meeting ends of thesectionsofthe wall 15, I interpose packing or washers 16 of leather orsimilar material which have their inner edges projected into the bore ofthe sections so that they will bear upon the lioats or buckets 5 andeffect a. water seal therewith to prevent the entrance of water into thecylinder. 'The outer wall 14 of the cylinder is constructed with anannular' inwardly projecting shoulder 17 at its lower end upon which issecured a collar or lugs 18 to which the lower end of the lowermostsection of the inner wal'l 15 is secured. In the upper end of the outercylindrical wall 14 I secure a Specitlcation of Letters Patent.

Application filed November 6, 1918. Serial No. 261,375.

collar or ring 19 which fits closely around the uppermost section 15 andin the said ring or collar 19 I mount adjusting screws 20. Theseadjusting screws have their lower ends bearing upon lugs or brackets 21on the side of the uppermost section 15 and it w1ll be readilyunderstood that by properly turning the screws, pressure will be exertedu pon the said lugs so that the several sections of the innercylindrical wall will be forced together and securely clamp the washersor packing rings 16.

The water-elevating members 5 are hollow substantially cylindricalbodies having a flat head 22 at one end and at the o posite end having acup-shaped head 23 which extends into the body as clearly shown in Fig.2. The heads are both formed integral with the side walls of the body orermanently sealed therein so that the bo y will be air-tight and Iprefer to exhaust the air in the 'course of manufacture so that theinterior of the bodies will be practically vacuums. The adjacent bodiesare flexibly connected by rings 24 so that an endless chain will beformed, and the bodies are so dis posed that the concave or cup-shapedend' will be uppermost as the body rises through and from the water. Thewater-elevating members should be of such dimensions that they will fitclosely within the several packing rings 16 and at least two of saidmembers will be within the cylinder at all times.

It is thought the operation of the device will be readily understood.The several hollow bodies pass downwardly through the branch 10 of thepipe 9 and move upwardly through the cylinder 13, the result being thatthe water in the well will flow into the cups at the upper ends of theseveral bodies and each body will consequently lift a certain quantityof the water which will be delivered into the spout 6 as the severalbodies pass over the pulley or wheel 4. The branch l() of the pipe 9serves to guide the water-elevating members as they pass down into thewell and holds the pressure of the water from the same so that they willmove in a rectilinear path to the return bend 12. The water cannot enterthe cylinder 13 and thereby reach the pipe 9, inasmuch as the engagementof the water-elevating members with the packing rings 16 forms anei'ectual water seal and any small quantity of the water which may4possibly enter the upper extremity of the cylinder will be immediatelycaughtby the cup-'shaped upper end of the member 5 which ma beimmediately adjacent the top of the cylinder. As the said members 5 arefree in the open water above the cylinder 13, the strain upon theoperating mechanism will be minimized and the water will be raisedrapidl andl easily and without an particular e ort.

In t e use of the improved water elevating apparatus, the operation ofthe handle or crank 25.01? the wheelresults in the movement of theendless chain over the wheel whereby the hollow air-tight bodies uponleavin the cylinder 13 will ick up a quantity o the water and disc argethe same through the spout 6. During the downward movement of thebuckets or hollow bodies, the same are spaced -from contact with thewater so as to remove the resistance which would otherwise be offered tothe buckets on their downward movement.

Having thus described my invention, what is claimed as new ist l. Thecombination-with a well, of a wheel arranged at the upper end of thewell and having operating means, an endless chain trained over saidwheel and comprising a plurality of hollow air-'tight bodies and meansconnecting the bodies, one end of each bodybeing cup shaped for formingwater receiving means, a pipe'receiving said chain and formed adjacentone end with abend thereby forming a long chain inlet vbranchterminating above the level ofthe water in the well and a short outletbranch terminating below thel water level, and a cylinder arranged atthe discharge. end of said outlet branch and having means providing awatertight connection between the same and 'the hollow air-tight bodies.

2. A water elevating apparatus for wells comprising a wheel havingoperating means,

. sald chain and formed adjacent one end with a bend thereby forminglong and short branches, said long branch terminating above the level ofthe water in the well and constituting a chain receiving means, saidshort branch terminatin below the level of the water and constitutin achain outlet means, and means to exc ude water from said short branch.

3. In a water-elevating apparatus, the combination of a pipe to besecured within a well and having two vertical members connected by areturn bend, one of said vertical members having .its upper end abovethe water level in the well and the other vertical member having itsupper end below the water level, a cylinder within the shorter branch ofsaid pipe consisting of a plurality of axially alined superposedsections, pack ing between the meeting ends of adjacent sections, meansfor clamping said sections againstl the packing, an endless chain ofwater-elevating members movable down wardly'through the longer branch ofthe pipe and upwardly through the said cylindrlcal sections, andoperating means connected to said water elevating means.

In testimony whereof I aiiix my signature.
